My piggies still make a bit of a fuss whenever i try to get them out but they seem find once there out.
Do you have any cuddle sacks or fleecey blankets they can cuddle up in when they're out with you ?
Guinea pigs love feeling safe so being cuddled up in something cosy is the best way to win there trust, my newest piggy Marmite loves my mums fluffy dressing gown so she use to wear that and he'd snuggle up on her shoulder.
Some people recommend short and often with piggy handling for a new pig but i prefer to keep them out for a while as the stress of getting them out isn't pleasant for them so maybe if your watching a film or just something on tv something get a nice fleecey blanket and let them snuggle up, also the fleece will stop any pee from getting on you ! and poops !
Marmite enjoyed just being there with the sound of the Tv at first he didn't really like the sound of us talking so maybe try just a really relaxing sit down dimmed lights maybe in the evening.
Don't forget food is the way to a piggies heart ! Marmite wouldn't let us hand feed at first where as Bentley and Chester have always done that, so i guess it depends on the piggy. Offer them some food and if they don't take it just leave it in front of them and allow them to sniff it and eat it in there own time (:
